This question usually gets answered with a range. Three to five hours, say. It sounds helpful and is almost useless. The same range covers a small apartment and a large family home, a maintenance visit and a first deep clean.
Hours are the result of four variables. Once you know what they are, you can estimate your own home reasonably well, and you can tell whether a quote you have been given is realistic.
Variable one: which service, not which house
Service type is the single biggest factor, and it dwarfs square footage.
A standard clean works surfaces in one top-to-bottom pass per room. A deep clean adds a detail phase before that pass: grout, tracks, frames, vents, hard-water removal. All of it mechanical work, none of it rushable. A move-out clean adds every cabinet interior, every closet and every appliance interior on top.
The same house can therefore take dramatically different amounts of time depending on what has been booked. Comparing durations without comparing scope tells you nothing.
Variable two: bathrooms, not bedrooms
People instinctively describe their home by bedroom count, but bathrooms drive cleaning time far more.
A bedroom is largely dusting, a bed and a floor. A bathroom is a shower or tub, glass, grout, a toilet worked completely including the base and the wall behind it, a vanity, a mirror and a floor with edges, all in a small space where everything needs a different product.
A three-bedroom home with three bathrooms is a longer visit than a four-bedroom home with two. If you want a useful estimate, lead with the bathroom count.
Variable three: condition
Condition is why a first visit and a maintenance visit to the same address are different jobs.
On a maintained home, the team is removing two weeks of ordinary use. On a home that has not had professional cleaning, they are removing accumulated build-up: grout that has never been worked, cabinet fronts carrying months of cooking residue, hard-water film that has bonded to glass.
The second job can take twice as long as the first, in the same house, with the same scope on paper.
Variable four: how many people arrive
A team of two does not quite halve the time of one person, because shared equipment and coordination cost something. It comes close, and it changes what is possible in a day.
This is why a company can complete a move-out clean against a same-day closing deadline where a single cleaner realistically cannot. If you are working to a fixed hour, team size matters more than any other factor.
Rough shapes, with the usual caveat
With all four variables stated, some general shapes are still useful, as long as they are read as shapes rather than quotes.
A maintenance visit on a mid-sized, well-kept home is a half-day job for a small team. A first deep clean on the same home is meaningfully longer, often close to double. A move-out clean on an emptied property of the same size sits between the two, because there is no furniture to work around but every cabinet and appliance interior is in scope.
Any company quoting your specific home should be asking about bathrooms and condition before giving a number. If they are not, the number is a guess.
Why hourly quotes and fixed quotes behave differently
An hourly arrangement means you carry the risk of the estimate being wrong. If the home takes longer than expected, you pay for it.
A fixed quote for a defined scope moves that risk to the company, which is generally better for the customer. It only works if the scope was described accurately in the first place. This is why a good company asks detailed questions before quoting rather than after arriving.
Whichever model you are offered, ask what happens if the home turns out to be in worse condition than described. A straight answer to that question tells you a lot.
